Every day the results of Clan Wars are announced, and top 20 clans that earned the largest amount of Glory points get a special reward: Artifacts. They will be given out to each player who won at least one battle that day.

Additionally, you receive 1 artifact for each battle won in a series of 3 wins, and scoring 5 Clan War wins grants you 2 Artifacts.

You can check the Artifacts available to you in the Psi-generator in your base.

In order to get a weekly clan reward, you need to take part in Clan Wars regardless of wins or losses.
